Explanation:
The cellular communication is an important aspect of unicellular and multicellular organisms in the environment. The cellular communication may differ in the bacteria, plants and animals but the mechanism of cellular communication remains the same.
The mechanism involves the receptors, change in the structure of receptors which triggers the signal to respond and then the response of the cell. Therefore the evolutionary biologists must look at this mechanism and the molecules associated with this mechanism.
The biologist can look at these receptors and the ligands which initiate the transduction process in the organisms.
Independent of whether an organism is an endotherm or ectoderm, the least reliable indicator of an animal's metabolic rate is the amount of water consumed in one day. The metabolic rate is the speed at which chemical reactions take place in the body and varies because of several factors including age, gender and inherited factors. It is also affected by the proportion of muscle to fat in the body , amount of exercise and other physical activity.
Chemicals that help chemical reactions occur at faster rates in living organisms are known as Enzymes.
